Copycat WE fix

Copycats+ blocks keep their old material orientation when WorldEdit flips or rotates them, because the disguised material inside a copycat block is not turned along with the block itself. Multi-part copycats such as the copycat byte, copycat byte panel, copycat board and copycat slab are affected more, since half layers and corner faces can end up with the wrong materials. This mod patches the paste step so that horizontal flips on the N, S, E and W axes, and rotate commands, produce correct results.

The fix only touches paste operations that run with a flipped or rotated clipboard, so existing builds stay untouched. It also changes how Create's own schematics behave, and it adds commands and a configuration file for install and forget actions. Non-copycat blocks such as signs, banners and vanilla blocks are modified too. Vertical orientation results for other copycats remain imperfect, because Minecraft has no Y-axis mirror. The mod requires Create and Create: Copycats+, and WorldEdit is optional. It is installed on the server only, so players do not need it.
